Repairing cracks in plastic parts
The 3M 05900 repair kit remains today the most reliable way to glue broken plastic parts. It is not difficult to work with it, since step-by-step instructions are included in the package.
For those who will do this, I can give only one piece of advice regarding preparing cracks for gluing: to give the crack a V-shape, use a utility knife blade. Just be sure to take precautions. Put a thick glove on your left hand, and wrap the blade itself halfway with electrical tape.
Spray paint from selection
A tricky knight's move, a secret ace up your sleeve when you know about the possibility of filling a spray can with selected paint. This service is provided in some selections. You can find your own color or choose a rare one that is not in regular lines, fill it in a bottle (this takes about 100g) and paint it in a color as close as possible to the original or one that is not on the shelves.
However, do not forget that the same paint codes may differ in shade; if you buy cylinders from different companies, there may be errors in tone
The final step is to use varnish. It is also sold in aerosol form. Even though applying varnish requires experience, using a can greatly simplifies your task.
As a result: if it is impossible to work in good conditions with professional equipment or if there is strict cost/time savings, materials in the form of aerosol cans are the most optimal solution.
Scooter plastic painting
The main problem when painting plastics is poor adhesion of paints and varnishes to the surface of the plastic. But chemists found a solution and created a product under the scientific name adhesion promoter.
In the retail chain, this product is often referred to as 1K primer for plastic, although, in fact, it is not a primer. Often inexperienced painters call the same material a plasticizer, which is also completely wrong. The plasticizer is a thick, clear liquid used for painting very flexible plastics and is added directly to the primer, acrylic paint or varnish, while the adhesion promoter is applied directly to the bare plastic.
Painting a scooter is almost no different from painting a car bumper. The only difference is the different color scheme. In other words, you most likely won't find the exact same paint, even in a color matching lab. There is only one way out - to paint the part completely, in a similar car color.
Graffiti paint
This option is chosen by lovers of bright colors. Graffiti balloons have a huge selection of colors. There are more tones in the color catalogs for street art than there are options for the color of nail polish for your beloved's manicure.
An indisputable plus for the team of these materials is their survivability. They were developed to be applied to completely different surfaces, from brick to wood, with a discount on weather conditions - rain, frost, etc. And if you put in your work, it will definitely please you for more than one season.
Spray cans for graffiti also have a useful option - the ability to choose caps. Cap is a spray can nozzle that regulates the paint flow. Manufacturers of graffiti spray cans have created entire sets with caps. With their help, you can control the width of the paint spray, create thin, rounded or oblique lines.
Provided that the base tone is snow-white, one and a half layers of bright color from a graffiti spray can create truly delightful shades of expression.
Briefly about the work procedure
1. Remove damaged parts from the scooter and wash them thoroughly with laundry soap, leaving no traces of oils.
2. Glue the cracks according to the repair kit instructions.
3. Using polyester putty, achieve final evenness of the seam.
4. Apply one thin coat of adhesion promoter to the exposed plastic.
5. After ten minutes of exposure, apply 2-3 layers of acrylic primer.
6. Sand the primer with P 800 abrasive and apply 2 layers of paint.
7. If you have metallic or pearlescent paint, you need to apply a clear varnish after 40 minutes.
Most often, scooters are painted in two or three colors. To speed up the process, you must first apply different enamels one at a time, and then 40 minutes after using the last one, apply varnish to all parts at the same time. The difference in waiting time before applying enamel does not matter for each individual paint.
And one more important note. During preparatory work for painting a scooter, clean gloves should always be worn on your hands. This will protect the skin of your fingers from being rubbed by rough abrasives.

Existing dyeing methods
Gone are the days when car enthusiasts who wanted to do the painting themselves could only use nitro enamel, and, as a last resort, used oil and pentaphthalic paints. Now new chemical compositions have appeared, thanks to which it is possible to paint rims in several ways:
- using acrylic paints sold in aerosol cans;
- application of polymer coatings;
- the old method is painting with automotive nitro enamel;
- laying a layer of so-called liquid rubber;
- chrome plating

Not all of the options listed are suitable for implementation at home. Take a polymer (powder) coating that is very resistant to environmental influences and mechanical damage. It is applied using a certain technology, consisting of the following stages:
- Surface preparation, including degreasing.
- Priming with a special composition.
- Application of powder enamel.
- Curing the paintwork in an oven.
Since not every home has an oven for heat treatment of painted products, this method is not suitable for the average car owner. Unless you go to a specialized auto repair shop, where they will apply the polymer with high quality and charge a decent price.
For the same reasons, it is almost impossible to perform chrome plating at home. This is a complex technological process that includes the sequential application of various components with several intermediate rinses with distilled water. Moreover, the time for placing chemicals on the surface is strictly regulated. Therefore, to give the wheels the effect of a chrome surface, you will again have to turn to professionals.

Surface preparation
To get the desired result, you need to carefully prepare the material. How to prepare plastic for painting? Do the following:
- Remove the old coating; solvents and sandpaper are suitable for this purpose.
- The surface is cleaned.
- Degreasing step.
- Application of antistatic agent.
- Putty is applied as needed.
- Processing with sandpaper, then cleansing again, removing fat.
- Padding.
- Grouting, cleaning.
Pros and cons of painting castings and spray stamping
The use of aerosol paint is becoming more popular when repairing cars. The reason is that there is no need to purchase a spray bottle, which you also need to know how to use correctly. In addition to setting up the tool, you need to maintain the required distance to the surface and apply the product evenly at the desired angle. You also need to dilute the paint to the required consistency for the spray gun.
The can is immediately ready for use; it only needs to be shaken well first. However, only expensive compounds can give high-quality results. Cheap types usually don't do the job up to par.
In addition to the quality of the paint, the release of the composition from the aerosol also plays a role, so that the paint is distributed evenly and without smudges. A reusable coating is made; the layers must dry well before applying a second one. The spray pressure is low, which is not the case when working with a spray gun. Also, the pressure level during operation will change.

Low profile in inches
As the name suggests, it is used for low-profile tires. Example: 4.25/85H-18. The first number is the tire width in inches, the second is the profile height expressed as a percentage of the width, H is the speed index, 18 is the rim diameter.

Why do you need to paint alloy wheels?
Painting the casting has not only a decorative function; the paint also helps to protect the wheels from negative factors. Therefore, when painting car or motorcycle rims, it is necessary to choose a suitable composition that will withstand constant loads so that the layer does not crack or fall off. If the layer falls off, then rust will appear in this place over time, and the external design will no longer be beautiful.
The following are important reasons to paint wheels:
- Salty material that road services sprinkle on the road during the cold season. When sand, salt and snow are mixed, the conditions for the wheels become negative. Discs are in a special risk zone; sometimes noticeable changes on their surface appear after two winter seasons. At the moment there is no effective remedy for protection against this factor;
- Country roads are expensive, such coatings also have a bad effect on the integrity of the disc surface. The presence of small particles and stones in the soil base leads to damage to the material, which contributes to the formation of rust and oxidation of the metal base. As a result, scratches appear and the appearance of the painted layer becomes unsightly;
- Significant temperature changes. Coloring allows you to avoid distortion of the disc size under the influence of temperature changes; this phenomenon is not uncommon in our country. As a result, the paint will fall off.
These reasons explain the need to paint the disk elements. Specialists will cope with the task without any problems, but their services are not cheap. For this reason, you can learn how to paint alloy wheels yourself. If you adhere to technology, you can carry out the process correctly at home.
Painting the casting has not only a decorative function; the paint also helps to protect the wheels from negative factors.
